Protein requirements of preschool children consuming rice-milk, rice-toasted mung bean, and rice diets


Rice-milk and rice-toasted mung bean diets, and a high-protein rice (IR58 milled rice) were evaluated as part of a study on the protein requirements of toddlers consuming rice-based diets following the multilevel N balance method. Milk or mung bean contributed 1/3 of dietary N. At a daily energy intake of 418 kJ/kg body weight, weight losses were observed for all diets. The safe level of protein intakes obtained allowing 10 mg N/kg body weight/day for miscellaneous integumental losses and 15 mg N/kg body weight/day for growth was 1.11 g/kg body weight/day for the rice-milk diet and 1.34 g for the rice-mung bean diet. Preliminary data on four children indicate a safe level of protein intake of 1.44 g/kg/day for the IR58 milled rice. The protein quality of the high-protein rice as determined by the very short term N balance index on three children was 79–80% relative to milk.
